Cod Liver Oil for Dogs

What are the benefits of cod liver oil for dogs?  Your pet deserves a healthy and nutritious diet to support growth and vitality. In the past, the canine diet consisted of a variety of natural, unprocessed foods.  Unfortunately, with the convenience of processed pet foods, we may not be giving our favorite companions all the nutrients they need for optimal health.

One of the items high the list of missing nutrients may be omega 3 fatty acids. Omega 3’s are special fats that help support a healthy cellular environment and have been found to fight inflammation.

Your dog’s food may contain adequate levels of omega-6 fats from vegetable oils, but are you giving enough omega 3’s for your dog? If not, you may need to need to supplement with a high quality omega 3 supplement, such as cod liver oil.

Watch your Omega 3 to Omega 6 Ratios

cod liver oil dogsResearch has shown humans should strive for a ratio of omega-6 to omega-3 of 1:1 in their diets.  On the other hand, veterinarians recommend a ratio of omega-6 to omega-3 of 5:1 to 10:1 in dogs.

Cod liver oil contains the essential fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These nutritious fats provide the framework for growing a healthy skin and coat, flexible joints, strong heart, sharp eyesight and youthful energy.

Giving fish oils to dogs may address any possible nutritional imbalances in your pet’s diet and could help improve your dog’s overall health.

The Inside Scoop on Fortified Omega 3 Dog Foods

science diet omega 3 dog foodNow you can get specialized dog foods that have omega 3 fatty acids added to them. However, make sure to look at the label to see what the source of the omega 3’s are.

Many dog food manufacturers may use plant sources of omega 3 fatty acids. For example, flaxseed oil is an excellent plant source of the omega 3 fatty acid, alpha linolenic acid (AHA), and it’s commonly added to some dog foods.  Unfortunately, flaxseed doesn’t provide any EPA or DHA, only AHA.    Some veterinarians recommend your source of omega 3 fatty acids should provide adequate amounts of EPA and DHA. One of the best sources is nutritional supplements such as fish oils or cod liver oil.

With the convenience of modern day nutritional supplements, you can now give your dog cod liver oil capsules or liquid.  Many people simply pour the cod liver oil directly into the dog food or pierce a fish oil capsule and mix its contents into the feed.


Choosing the Best Cod Liver Oil for Dogs

So now that we know the benefits of giving our pets cod liver oil, how do you choose the right one for your dog?  I did an internet search for “cod liver oil for dogs” and found there aren’t a lot of companies that manufacture cod liver oils for dogs.

cod liver oil for dogsOne company that did catch my eye was Nordic Naturals. This company has been producing fish oils and cod liver oils for the last 20 years. They have a wide range of pharmaceutical-grade fish oils for both humans and animals.

All their fish oils go through extensive third-party testing to ensure there are no detectable levels of heavy metals, environmental toxins and other contaminants.  They claim to use fish from only the cleanest ocean waters. This is to ensure you’re getting a fresh, pure fish oil that won’t cause fishy burps, won’t become rancid, or have a bad taste.  They have a cod liver oil called Nordic Naturals Pet Cod Liver Oil for Dogs & Cats. These fish oils are specially formulated for pet consumption.

To ensure these are safe for your pet, they don’t come flavored with rosemary or other flavorings found in other omega 3 supplements.

Here’s what you get in a bottle of Nordic Naturals Cod Liver Oil for Pets:

One teaspoon dose provides:

  • Derived from 100% Arctic cod

  • 625 mg DHA

  • 410 mg EPA

  • 225 mg other omega 3 fatty acids

  • Vitamin E – 7 iu

  • Vitamin A – 450 iu minimum

  • Vitamin D – 2 iu

Suggested cod liver oil dosages for your pets:

Dogs: 0 – 20 lbs – 1/4 teaspoon

20 – 55 lbs – 1/2 teaspoon

over 55 lbs – 1 teaspoon

Directions for Use: Apply oil directly to food or serve by itself.

I think this is a really good product to use for your dog or cat. You can get it 8 oz and 16 oz bottles and Suggested Retail prices are $19.99 for the 8 oz bottle and $39.99 for the 16 oz size. If you shop around, you may find them at cheaper prices, both online and in your local pet food store.
